A home node aware replacement policy for a cache chooses to evict lines which belong to local memory over lines which belong to remote memory, reducing the average transaction cost of incorrect cache line replacements. With each entry, the cache stores a t-bit cost metric (t>=1) representing a relative distance between said cache and an originating memory for the respective cache entry. Responsive to determining that no cache entry corresponds to an access request, the replacement policy selects a cache entry for eviction from the cache based at least in part on the t-bit cost metric. The selected cache entry is then evicted from the cache.
